    They are Probably Better than a lot.. Individually Pressure tested under water.. Nev

    Be grateful for ANY service . There's no guarantee they will still be in business, tomorrow.. Nev

    Aero engine Makers Modify things that Come up in the field/service if a Part proves Problematic.. It happens all the time. It may Be a change of material spec or Heat Treatment or adjustment to operating procedures. Mass of the engine Matters more than in Most other Power plant applications and compared to Many other Production runs are Low Volume so it's not a great Market to get Involved with IF you want to get rich without headaches.

    I don't believe (and I've looked extensively) that there IS another Maker for this spec of filter, and I have given my reasons why there isn't. Your statement is a supposition. Meets or exceeds OEM specs is not mentioned, in relation to these Motors re other options Try getting that assurance.. You fellas's hang on every Word Rotax say normally but choose to ignore their recommendations on Oils and filters? Excuse Me, but I don't get that. These Motors have complex, and often conflicting lubrication requirements. And you say you want to save a few Bucks? You have your Priorities WRONG. Nev

    Cent wise, dollar foolish. Wrong answer. IMHO. Nev

    Not usually, when it's about safety. Safety is MY thing remember. . I know it's Boring but Maybe someone will benefit from it, or Perhaps HAS. I'm glad you realise I'm Funny ha ha sometimes. Thanks. Nev

    I don't think it's about warrantee games at all, but they DO have to protect themselves. Why not use the Best available? Possibly and Probably, don't register in My Aviation Brain. .Planes fly UP in the sky. Why increase your risks? Nev

    I realise that, but is everything a JOKE here? That's MORE for the Other Place. Nev

    Rotax are continuously up rating their Oils and filter requirements as they Push output's Higher. To suggest the Previous oils etc. would be still be OK is extremely Irresponsible. Nev

    Clearly it's a TYPO. Correct cruise speed should depend on wt. and headwind.. Think on that. Nev

    Saving cost is his "Thing'. Just fly while you can and get on with it. I doubt you'll find an equivalent filter, and you'd risk your warrantee, and safety. A Hair is 70 Microns. This filter is 20 and better in other ways. Why would larger/other filter Makers go to the trouble for such a small Market? Nev
  13. facthunter
    It's a 20 Micron Filter and they always cost more. Just find the best Price and stick with it. It's NOT a Car type engine in a lot of ways. By-passing should only be possible if the Environment is cold and the Oil is not warmed up as required OR the filter is blocked. Serviced at Normal Intervals should Preclude this happening. Cut used filter open at each service. Nev

    I would be very surprised IF you don't get 100 Kts TAS. Cruise. Nev

    An example using few machines that Vary a lot in the way they are used means very Little. Dust and short trips Make a lot of difference and whether you thrash it before the Pistons have reached their correct running fit.. Drain Oil while hot etc, On forums discussing Oils etc you Get the greatest Concentration of CRAP that you are likely to encounter, anywhere. Nev

    I doubt that they MAKE their own filters. Filters DO vary in the Micron figure and other aspects of Quality. IF there is a Piece spot welded on the end for a spanner some of them have had cracks forming at the spot welds. Also a poor thread fit means grit can pass there and the thread is weakened if a Loose fit. Sometimes the thread will bottom out before the seal, seals There's a few things you have to check. Nev

    Isn't there supposed to Be a DOG there to watch this sort of thing. Nev

    Bypass pressure is not the Be all and end all of anything. It should be a rare occurrence to allow unfiltered oil to Pass. (emergency), like filter blockage. Delivered oil under these Circumstances will be at a pressure Lower than normal by the By pass figure. Depending on where you Measure the Oil Pressure you may not even be aware of it Happening. IF this Happened it would be difficult to say the engine was not damaged. It's NOT the Normal way to operate. It's an "Any oil is better than not having any/enough", BUT how can you guarantee that there's NOT a great Lump of grunge going somewhere it will do Harm from a Blocked filter? Some times a Bypass valve is in the filter Mount casting and the Oil can Bypass without going anywhere near the filter element itself, so risk of contamination is reduced. It could also easily be fitted with a warning indicator . Nev

    Related to any Weight & Balance changes, Mainly. Nev
  20. facthunter
    I have pointed out advantages but not linked to actual landing judgement. It's mainly the Indication/confirmation of stall safety Margins in various configurations and weights and manoeuvres.. Very useful if you have a complex Flap /Slat retraction schedule. It doesn't show overspeeds etc Just AoA related stuff. Nev

    Have you guys done this sort of thing, Before? You would be better to stagger your arrivals. You have to be sure you know where everyone is along the way. It's extra risk and effort..Nev
